SAFETY FEEDING DEVICE FOR WRINGERS Filed April 12, 1933 3 Sheets-Sheet 3 Patented Nov. 7, 1933 UNITED STATES PATENT OFFICE Claims.

This invention relates to safety feed devices for roll wringing mechanism.

One of the objects of the invention is in the provision of a safety feeding device for roll wring- 5 ing mechanism so arranged as to permit the automatic feeding of garments to the wringer rolls without danger to the operators hands.

Another object is in the provision of a safety feeding device which comprises an apron member disposed adjacent the wringer rolls and driven thereby, said apron member operating to continuously feed the garments placed thereon into the wringer rolls, and thereby obviating any possibility of injury to the operators hands.

Still another object is in the provision of a safety feeding device composed of an angularly disposed apron or feeding portion which is driven by frictional contact with the wringer 'rolls, said apron member having a quick detachable connection which permits its ready placement upon either side of the wringer to accommodate the operator in any of the washing operations.

A further object is in the provision of a safety feeding device for roll wringing mechanism which includes an apron member, a support and framing means therefor and a detachable suspending means for the apron, which permits the apron to frictionally contact the rolls by gravity and to be driven therefrom.

A still further object is in the provision of a detachable safety. feeding apron mechanism which is driven by frictional contact with the wringer rolls, the detachability of the safety feeding device permitting its ready removal from the wringer and therefore insuring ease in shipment.

An additional object is to provide an apron type safety feeding mechanism having means for automatically engaging and operating a water shed member whereby water falling from the 0 wringer rolls is diverted toward the side of the wringer to which my feeding device is attached.

Another object lies in the provision of an apron type of safety feeding mechanism for roll wringing devices, said apron member including driving mechanism comprising roller members frictionally contacting the movable wringer rolls and through certain driving mechanism operating the apron in such manner as to present the garments placed thereon directly to the wringer rolls without any possibility of injury to the operators hands, said safety device not only having quick detachable mounting but also being so suspended upon the wringer in a manner to enhance the over-all appearance of the wringer and washer upon which it is mounted.

Before referring to the specification for a detailed description of the invention, applicant desires to call attention to several classes of safety devices which are well known to the trade.

The ordinary type of safety mechanism for roll 35 wringing devices comprises a safety release mechanism which is adapted to be manually struck by the operator, which in turn results in the explosion of the wringer and consequent release of tension between the rolls. Many and varied attempts have been made to dispose this manually operable safety release member in such position as to absolutely insure explosion of the wringer. However, a safety device of this character is adapted to be operated following an injury. a 1

Again, we find various types of chutes and roller mechanisms upon which the garments are adapted to be placed by the operator for presentation to the'rolls. However, it isbelieved that applicant, for the first time, presents a safety feeding device which has the practical advantage of detachability necessary in the shipment of the wringer and also the additional advantage of being power driven from the wringer itself to the end that the garments will be continuously and automatically conveyed to the wringer rolls without necessity of the operators placing his hands in any; proximity whatsoever to the moving wringer rolls.

secured studs 33.

Referring to the drawings, Fig. 1 discloses a conventional wringer structure generally designated as 10. Since the invention herein described comprises an attachment for wringers, which may be of any make or type, it is thought unnecessary to describe the wringer structure further than to say that the device comprising my invention is attached to a wringer by means of hooks 11 which are secured to end portions of the frame thereof as indicated in Figs. 1 and 2, and further that the wringer is provided with a rockable water shed member 10 which is adapted to be engaged and operated by a portion of my feeding device, as will be described.

Figs. 5, 6 and 7 will indicate that my feeding device comprises a pair of housings 12 generally comprising cupped inner portions 12' having outer cover members 12" secured thereto. The housings are joined by means of a plate 13,

the whole forming a substantial framework "suitrollers-16 and 17.

As indicated in Fig. 3, the rollers 16 and 17' comprise bodyportio'ns 18 made from wood or other suitable material, to either end of which is secured ferrule members 19,: the same having integrally formed flange portions 20 and trunnion portions 21. As clearly shown in the several views, the rollers are somewhat contracted at their ends and this, together with flanges 20, provides suitable trackage for apron l5.

' Rollers 16 and 17 are supported in housings 12 by means of the trunnions 21 journaled in bearings 22 formed in theinner surface of the housing members 12. I

Within the largerlower ends of each of housings 12 are friction wheels 23 fotatably supported in the housings by means of pins 24 the wheels being mounted upon 'the'pins by means of hubs formed by extending boss portions 25 of pinions 26 which oecupy cavity portions 27 of the wheels. The pins 24, pinions 26 andwheels 23 are secured into a unit assembly by"means of pins 28 which pass through the three members as shown. The friction'wheels have an outer facing '29 composed of rubber or other suitable friction material and are freely rotatable in bearings 30 formed in housing memberslz and 12".

The trunnions 21 of roller 16 have pinions 31 removably secured to the latter and these are adapted to mesh with pinions 26 of wheels 23 as "shown.

'lnview of the foregoing, it will be clear that rotation of wheels 23 will result in rotation of roller 16 in the oppositedire'ctiom'with corresponding movement of apron 15' and rotation of'roller 17 This feature will be referred to shortly." i

Figs. 5, 6 and 7 will illustrate ear or bracket members 32 secured to either of housings l2 and extending" generally outwardly and upwardly therefrom. r

' In the uppermost portion of the brackets are Mentionof hooks 11, as secured to the wringer frame, has already been made. c

Reference to Figs. 1 and 2 will show that studs 33 are adapted to engage in hooks ll to form a support for the mechanism whereby the mechanism is pivotally supported adjacent the wringer rolls-in such a manner that the weight of the device is available to maintain 'friction wheels friction between 23 in pressure contact with the lower roll of the wringer.

The plural hooks 11 provide means for attachthe feeder to the wringer in several angular itions as indicated in dotted lines in Fig. 2. "s the may be adjusted to meet reqtnernents of practical use.

Considering the foregoing description, it will be apparent that removal and replacement of apron 15 may quickly be accomplished by removal of a cove; ..e -ber' 1r from one of the end housings exposing the underlying friction whee- 23 which may then be removed, exposing pinion 31 v ch then be withdrawn from trunnion 21 iereupon housing portion 12 may be removed f1 ill the trunnions exposing ends of rollers 16 and 17 to permit removal and rep cement of the apron. Reassembly is accomplrs d by manipulation of the parts in reverse order.

It is th ught that the foregoing has described the struc e and operation of feeding device suit. ..entiy to obviate further description; however, opera on of the device may be sumas shown in Figs. 1 and rotation of the wringer rolls in the direction of the arrows will, through the lower wringer roll and wheels 23, cause corresponding rotation of roller 16 to move the upper surface of apron 15 toward the wringer rolls. With the wringer rolls rotating as shown, the apron is adapted to conduct materials toward and into the wringer, whereby the materials may be satisfactorily fed to, the wringer without need for an operators hand to be placed near to or in contact with the wringer rollers.

Thus, my feeding device provides a means whereby materials maybe fed to a wringer with perfect safety to both the operator and materials. I

The view shown in Fig. 8 wi l indicate the relative positions of friction wheels 23 and roller '16. The relative speed ratio between the wringer roll roller 16 is such that the apron surface moves at suitable speed relative to the peripheral speed of the wringer rollers.

It will be noted that by this arrangement the friction wheels which engage the lower wringer roll are located beyond the edges of the apron. This makes the device more satisfactory inasmuch as clothes which are within the confines of the apron itself cannot be caught between the wringer rolls and the friction rolls.

A water shed member 10 has already been noted asattached to the wringer mechanism.

Fig. 2 illustrates portions 12 extending downwardly from housing members 12 in such a manner as to' engage the rockable water shed member to maintain the same in position as shown in Fig. 2, whereby water falling from the rolls or feeder is automatically diverted back to its source.

Figs. 16 and 11 illustrate the convenience'with which the feeder may be attached to a wringer.

Fig. 10 shows the feeder about to be attached, with extensions 12 engaged with water shed lO'fwhile Fig.1l indicates continued manipulation to further operate the water shed plate and simultaneously bring studs 33 into position to engage hooks 11, also to bring friction wheels 23 into contact with the wringer roll. Further manipulation places the parts in working position shown in Fig. 2.
